BC Spaces for Nature’s wilderness conservation has focused on preserving BC’s Great Wild Spaces. These are vast natural areas of global conservation significance, are large enough to ensure that entire ecosystems, and especially large predator-prey wildlife populations, will survive over time. Such Great Wild Spaces will serve as earth’s premier sanctuaries for biodiversity, wildlife, and wilderness. BC Spaces for Nature has worked to create areas of this significance with campaigns to protect the Tatshenshini-Alsek and the Chilcotin Ark.
